Canon 420 EX Speedlite Flash [GN116] {Bounce, Swivel, Zoom} Description


The 420EX Speedlite is a medium sized flash for Canon EOS cameras.  This solid EOS system component combines great size and affordability with powerful features and sophistication.  Much stronger than a built-in or low profile flash, the 420EX has respectable power and bounce flexibility without being as cumbersome to pack and carry as a larger full-sized pro unit like a 550EX series flash.  It's a great travel flash or back-up unit or even slave unit to Canon's top of the line flashes.

Improving on the previous model, Speedlite 380EX, the 420EX has a head that can swivel left or right and the unit can also serve as remote slave flash triggered by a Canon 550 EX or ST-E2 commander.

The 420EX is compatible with digital EOS cameras and film EOS cameras.  Because it's capable of producing pre-exposure test flashes, the 420EX is compatible with EOS bodies that employ the first generation E-TTL camera flash system introduced in 1998 and also with EOS bodies using the newer improved E-TTL II metering system first introduced in 2005.

In 2005 Canon released the upgraded 430EX with manual power output control, flip down ultra-wide diffuser, and faster recycle time.  Because it has equivalent compatibility, equivalent maximum power, a dedicated slave mode switch, and a similar form factor at a lower price, the 420EX remains quite popular.
